Abstract
An additive process disk drive suspension interconnect, and method therefor is provided. The interconnect has a metal grounding layer of typically stainless steel or copper metallized stainless steel, a metal conductive layer and an insulative layer between the metal grounding layer and the conductive metal layer. A circuit component such as a slider is electrically connected to the conductive layer along a grounding path from the circuit component and the conductive layer to the metal grounding layer through an aperture in the insulative layer. For improved electrical connection a tie layer is provided through the insulative layer onto the grounding layer in bonding relation with the ground layer. A conductor is deposited onto both the conductive metal layer and the tie layer in conductive metal layer and tie layer bonding relation, and the circuit component is thus bonded to the grounding layer by the conductor.
